TURRET TOOL-POST.

To all whom it may. concern Be it known that I, Comm) M. Commo- SON, citizen of the United States, resident of Madison, county-of Dane, State of Wisconv of the lathe and therefore increase its capacity,-and a still further object is to provide a post for use on that class of work which cannot'be veconomically handled on an engine lathe or advantageously on a turret lathe.-

' The invention consists generally in various constructions and: combinations, all as hereinafter described and particularly pointed out in'the claims.

In the accompanying drawings forming partof this specification, Figurel is a vertical sectional view through a turret toolpost embodying my invention, Fig. 2 is a plan sectional view of the same, on the line w-c of Fig. 1, Fig. 3 is a vertical sectional view, taken on a line at right-angles substantially to the section line of Fig. '1, Fig. 4 is a sectional view on the line y-y of Fig. 3'.

In the drawing, 2 represents the longitudinal slide of the lathe and 3 the cross slide.

4 is a standard. mounted on the cross slide and projecting upwardly therefrom. The upper portion of'this standard is circular in form and preferably has an exteriorly threaded surface as at 5, and an interiorly threaded split collar 6 preferably encircles said standard and engages the threads thereon, and is provided with an operating handle 7 by means of which said collar may be rotated to raise or lower it, on said standard. Said collar is provided at its upper end with an inwardly projecting annular flange 8 that preferably fits within an annular groove 9' formed in the lower portion of aturret tool-post 10'and is providedwith a flat under surface having a series of notches Specification of Letters Patent.

11 formed thereon which are adapted to receive teeth 12 provided in the top of the standard 4, thereby locking the post on said standard against premature rotary movement and facilitating the indexing of the post in the operation of the machine. The post also has preferably a centrally arranged socket 13' therein adapted to receive a stud l4 concentric with said standard and projecting upwardly therefrom, and the walls of said socket have recesses 14 therein adapted to receive the finderball 15 that is preferably mounted in the stud 14 and yieldingly projected against the walls of the, socket by a compres .sion spring 16.- The walls of the socket are a rounded to fit the surface of the ball, and to enable the operator to easily turn the post on the standard, the entrance of the ball into the socket indicating each quarter revolution ofthe post and enables the operator of the lathe to accurately and quickly adjust the post. The post is provided with horizontal recesses 1 to receive the tools, which are clamped therein by suitable means, such as the bolts 18. A horizontal tool holder 19 is preferably mounted in the post 10 and capable of longitudinal and rotary movement therein, said holder being preferably provided with a series of notches 20, preferably four in number, which are adapted to receive teeth 21- provided on the lower end of a slide 22 thatis preferably mounted in the top of said post and is held against rotary movement bysuitable means, such as the spline or guide 23. The slide 22 has preferably a threaded connection with the lower end of a stud 24 that is mounted in a cap 25 and provided with an .operatinghan- .dle'26.- When this stud is revolved, the slide will be raised or lowered to withdraw its teeth from a notch in the tool post beneath holder may,

' lengthwise .volve it, with each quarter revolution and indicating locked against operator to grasp the tool holder and rethe plunger dropping into a'socket to the operator the exact position of the tool holder, and the fact that a notch is directly beneath the teeth of the slide. When the stud 24 is tightened, the tool holder will be both longitudinal and rotary movement; 5

' In using the post, the collar 6 is revolved until the opposing surfaces of the post and standard are separated by the raising of the can be rotated in the collar until the tool holders and tools are adjusted in the desired position with respect to the work. At such time, the horizontal tool post, when it tal holder J is used, the toothed 1 slide is loosened and the holder may then be moved and rotated as desired to set it in the roper osition. The withdrawal of the toot on t holderwill still allow the spring-pressed deon the slide.

, parallel to member having its axis at right angles subvice to enter the'recess and aid the operator in determining the proper rotation of the holder to'register the recess with the tooth When the orizontal holder has been'properly adjusted, the handle 26 may be operated and. theslide locked in engagementwith the holder.

In various ways the details of construction herein shown and described-may be modified and still invention.

I claim as my invention: Y 1."A turret tool post comprising two members, one ad'a ted to index in a plane the axis of the work, the other be within the scope of my stantially-to the axis of the first named member and carried thereby.
